Australia #508 (SG#508) 1971 Christmas Issue, a VFNH Block of 7 on HF/Dull Paper
A very fine NH se-tenant block of 7 of the 7c stamps from the 1971 Christmas Issue, printed on paper that gives a high fluorescent reaction on the front and a dull reaction on the back. The stamps were printed in sheets of 50, with the 7 designs occurring in rotation throughout the sheet, and the emerald green stamps forming two crosses in the middle of the sheet. So, these centre stamps are scarcer than the rest of the stamps in the sheet.
Another block offered in this sale has the same appearance from the front, but gives a low fluorescent flecked appearance on the back. The comparison scans show the appearance of both blocks from the front and back.
Scott lists this block at $30 for VFNH. This is a significant drop over the years. I can remember when these were selling for over $100 Australian in the 1980's. The block offered here grades 75 as follows:
Paper freshness: 5/5
Absence of visible paper flaws: 5/5
